JEANCON] EXCAVATIONS IN THE CHAMA VALLEY 39 
Plate 37, H, has a hatched design which is most common on the 
incised ware, only here it is painted instead of being incised. It is 
54 mm. in height and 63 mm. in diameter. The black design is a 
jet black. 
Both of these pieces are of a very hard paste and covered with a 
dirty white slip. Both have lugs, placed near the top and pierced 
so that a cord could be inserted for the purpose of carrying them 
or for hanging them up. There is no reason to suppose that they 
were not made at Po-shu, and yet they are so old a form and general © 
type in decoration and color that the fact of their being found there 
would indicate an antiquity for the ruin that is not borne out by 
other facts. There is also a possibility that they were brought in 
from farther west. 
HARD COILED WARE 
Closely allied to the late black and white, and probably contem- 
poraneous with it, is the blackish gray coiled and indented ware. 
These two are always associated in the finds in the ruins of the Jemez 
Plateau and the Rio Grande Valley. Unfortunately up to this time 
no exclusive black and white ruin has ever been excavated. At 
Po-shu the hard coiled ware is represented by a few sherds, some of 
which are marked with thumb indentations, some with stick in- 
dentations, and some showing the coil. They are all very hard and 
of much better paste than the later black cooking ware. (PI. 37, J.) 
Duck or Moccasin SHAPE 
Two of these eccentric forms are in the black coiled ware. The 
paste is somewhat harder than the late black ware and still not as 
hard as the early black ware. To what use the vessels were put is 
not known. In the smaller ones, which are not uncommon in cer- 
tain localities and which occur principally in the black and white 
ware, we sometimes find traces of grease and the sides and rim are 
burned. It has been suggested that these were used as lamps, but 
that would hardly hold good in the case of the ones from Po-shu. 
There is one from this ruin in the biscuit ware; this is decorated with 
birds (see fig. 33) and has lateral wings. The head was gone and no 
attempt has been made to restore it. These are all shown on Plate 38. 
PINCHED WARE 
There is only one piece of pinched ware in the collection. The 
author has never seen another specimen of the black ware treated 
in this manner. The paste is very hard and seems to belong to the 
early gray-black coiled ware. In making the embellishment of the 
pot, instead of incising or showing the coils the potter has pinched 
the clay along the upper sides of the pot and this has given a
